Abstract: 비휘발성 비파괴성 판독 강유전체FET메모리(10, 40, 60, 80, 100, 110, 120, 130, 160)는 반도체기판(19), 강유전체기능구배체("FGM")박막(26, 50, 70, 90, 20, 140, 170), 및 게이트전극(30)으로 이루어진다.   제1기본실시형태에 있어서, 강유전체 FGM박막(26, 50, 70, 90, 20, 140, 170)은 강유전체화합물 및 유전체화합물을 함유한다.   유전체화합물은 강유전체화합물보다 낮은 비유전율을 가진다.   박막내에 강유전체 화합물의 농도구배가 있다.   제2기본실시형태에 있어서, FGM박막(26, 50, 70, 90, 20, 140, 170)은, 강유전체화합물의 조성구배가 자유로운 히스테리시스거동으로 되는 기능구배 강유전체("FGF")이다.   FGF박막의 자유로운 히스테리시스거동은 강유전체FET메모리의 확대된 메모리윈도우와 관계가 있다.   FGM박막(26, 50, 70, 90, 20, 140, 170)은 액체소스MOD방법을 사용해서 형성하는 것이 바람직하고, 멀티소스 CVD방법도 바람직하다.
